sembled carton utilizing the United States Patent ce 3,337,037 BEARING PACKAGE Walter E. Thill, Grosse Pointe Woods, and Jerry E. Cardillo, Dearborn, Mich, assignors to Federal-Mogul Corporation, a corporation of Michigan Filed Mar. 10, 1965, Ser. No. 438,522 13 Claims. (Cl. 296-46) This invention relates to cartons for packaging bearings and more particularly to cartons for packaging shell-type bearings.

Shell-type engine bearings are semi-cylindrical parts having a steel backing with a lining material on the inside such as babbitt. The lining material is usually soft such that any engagement of this inner surface either by the carton or the other bearing half can damage the lining thereby either lowering the market value of the bearing halves or rendering the bearing halves unuseable.

In the past these bearing halves have been packaged with their inner surfaces in confrontation such as to define a circle and a diametrically extending separator was extended therebetween. While this construction protects each inner bearing surface from contact either by its mating bearing half or from contact with the carton, the arrangement is inefficient from the packaging standpoint since it does require a relatively large carton.

In the present invention the size of the carton is substantially reduced while the bearing halves are still maintained separated from each other and the respective linings protected. Therefore, it is an object of this invention to provide a novel carton for packaging bearing halves which can be substantially smaller than the conventional carton surfaces of the bearing halves are protected from engagement.

It is a general object of the present invention to provide a novel carton for packaging bearing halves.

Other objects and advantages of the present invention will be apparent from the following specification, claims and drawings, wherein:

Looking now to the embodiment in FIGURES .1

3331M? Patented Aug. 22, I967 through 3, the carton is generally indicated by the numeral l2 and has a bottom portion 14- and side wall portions 16 which are symmetrically disposed on opposite sides of the bottom portion 14-. Portions 18 are symmetrically disposed at the front and rear of the bottom portion 14- and are the front and rear wall portions, respectively, of the carton 12. The front and rear wall portions 18 are provided with flaps 29 on opposite transverse sides thereof which are folded inwardly and are utilized to secure the front and back wall portions 18 to the side wall portions 16. Portion 22 represents the cover or top portion with a locking flap 2d at its forward end. Separating or dividing portions 26 are secured to and extend transversely from the ends of the side wall portions 16 and with the carton l2 assembled as shown in FIGURE 2, are folded along the scored lines to partially overlay one of the bearing halves (shown in phantom in FIGURE 2). The separating portion 26 is provided with a tab 28 which is fixed to the remainder of the separating portion 26 along an arcuate scored line 30. The tab 28 has a portion 32 which adjoins the end portion 16 with the connection 34 therebetween being cut to facilitate bending along the arcuate scored line 30. The arcuate scored line 30 is provided to be of a radius substantially equal to the radius of the outer surface of the bearing halves such that with the tab 28 bent downwardly in the manner as shown in FIGURE 2, the tab 28 defines an arcuate surface which matably engages the outer surface of the rearward one of the bearing halves located within the carton 12, (FIG- URES 2 and 3). The tab 28 can be provided with a series of scored lines to facilitate bending. By bending the various portions inwardly along the scored lines indicated the portion 12 will assume the shape shown in FIGURE 2.

Looking to FIGURE 2 it can be seen that at the point of projected contact between the inner edge of the forward bearing half and the outer surface of the rearward bearing half, the halves are separated by the curved tab 28. It can be seen as in FIGURES 1 through 3 that with the bearing halves assembled in carton 12 as shown in FIGURE 2, no portion of the carton 12 can engage the internal surface of either of the bearing halves and note also that the two bearing halves are firmly held separated from each other whereby contact therebetween is prevented.

Several modified structures have been shown; in the description of these modifications, portions similar to portions in the embodiment of FIGURES 1-3 have been given the same numeral designation with the addition of a letter suffix.

In a modified structure shown in FIGURES 4 and 5, a d' erent separator portion 26a is provided having a tab 28a which is connected to the remainder of the separating portion 26a by means of a straight scored line 30a. Again the connection between the tab 28a and a side wall portion 16a is cut as at 34a such that the tab 28a can be bent along the straight scored line 30a. The scored line 30a is provided such that with tab 28a bent therealong (see FIGURE 5) it is tangent to the outer surface of the rearward one of the bearing halves substantially at the point of contact Pa between the bearing halves and hence maintains the bearing halves separated from each other.

In FIGURES 6 and 7 is shown a further modification in which the tab 28b is in contact against the outer surface of the forward bearing half at two points of tangency Pb and L. Here the separating portion 26b is provided with the tab 2812 which is connected to the remainder of the separating portion 26b by a pair of straight scored lines 30b which intersect each other at the juncture thereof and are separated by means of a cut 36 to facilitate bending. Again the tab 28b is separated from the. side by appropriate scored lines into a vall portion 16b by means of a cut 34b to facilitate Jending. Looking now to FIGURE 7, it can be seen that )n bending the tab 28b along the scored lines 30b, the )uter surface of the rearward bearing half is contacted it a point of tangency Pb by one section and at a second point of tangency L by the other section. Note that the point of tangency Pb occurs at the point of anticipated contact between the forward and rearward bearing halves. Thus the latter construction separates the forward and rearward bearing halves such as to prevent contact therebetween and also provides an arrangement whereby the inner surfaces of the bearing halves cannot be contacted by the edges or corners of the carton.

It should be noted that the cartons 12, 12a and 12b are of. a design to facilitate being folded by a machine. A different structure adaptable for folding by hand is shown in FIGURES 8, 9 and 10.

Looking now to FIGURE 8 the carton is generally indicated by the numeral 40 and is shown as a development and includes an elongated strip 42 which is divided front wall portion 44, which is connected to a first side wall portion 46, which in turn is connected to a rear wall portion 48, which in turn is connected to a second side wall portion 50.

The bottom portion 52 is connected to extend rearwardly from the side wall portion 44 and is provided with a tab portion 54. A top portion 56 extends forwardly from the side wall portion 48 and is provided with a tab portion 58. A cover tab 60 extends forwardly from the end portion 46 while a cover tab 62 extends forwardly from the end portion 50. A connecting tab 64 extends in the opposite direction from the front wall portion 44. A separating portion 66 extends forwardly from the side wall portion :6 and a similar separating portion 63 extends forwardly from the side wall portion 50. The separating portions 66 and 68 can be provided'with tabs similar to any of the tabs 28, 23a or 2812 and as shown in FIGURES 8 through 10 are provided with tabs similar to the tabs 28b which have two points of tangency or contact with the outer surface of the rearward bearing half. Since the tabs '70 and 72 are similar, only tab 70 will be discussed. Tab 7 0 is connected to the remainder of separating portion 66 by means of a pair of intersecting scored lines 74 which are cut at their juncture. Appropriate scored lines are provided to facilitate bending and the tab portion 76 is separated from the side wall portion 44 by a cut 76.

Note that in the embodiment as shown in FIGURES 8-10, the separating portions 66 and 68 when folded are located in engagement with the bottom portion 52 and hence the tabs 70 and 72 rise upwardly from the bottom surface as shown in FIGURE 10. The tabs 70 and 72 engage the outer surface of the rearward bearing shell at two points of tangency P0 and Le with the one point of tangency Pc being located at the anticipated point of engagement between the forward and rearward bearing halves. The connecting tab 64 is joined to side wall portion 50 and cover tabs 60 and 62 are folded inwardly over the bearing halves. Note that carton 40 can be opened either with the top or bottom portions 56 and 52, respectively.

Thus it can be seen with the embodiment of FIGURES 1, 2 and 3, the embodiment of FIGURES 4 and 5, the embodiment of FIGURES 6 and 7, and the embodiment of FIGURES 8, 9 and 10, novel structures have been provided for a carton of minimum size in which contact between bearing halves is prevented and in which engagement between the carton separating portions and the inner surfaces of any of the bearing halves is substantially precluded.
